A single-pass, cross-flow heat exchanger uses hot exhaust gases to heat water from 30 to 80°C at a rate of 3 kg/s. The exhaust gases, having thermophysical properties similar to air, enter and exit the exchanger at 225 and 100°C, respectively. If the overall heat transfer coefficient is 200 W/m2 . K, estimate the required surface area.
